[PATCH] D28166: Properly merge K&R functions that have attributes

[Reid Kleckner via Phabricator via cfe-commits]

rnk added inline comments.


================
Comment at: lib/CodeGen/CodeGenFunction.h:3570
     for (auto *A : llvm::make_range(Arg, ArgRange.end()))
-      ArgTypes.push_back(getVarArgType(A));
+      ArgTypes.push_back(getVarArgType(A, CallArgTypeInfo == nullptr));

> So, that didn't work at all, but the gist of it is that I don't think we should call a function like `getVarArgType` when we aren't lowering a variadic function call. I'll look into doing it.
rL290906 should fix it.
